HOSEiCLAMP TOOL.

Specication of Letters Patent.

Patented Sept. 29, 1908.

Application filed December 2, 1907. Serial No. 404,878.

To all whom 'it may concern.'

Be it known that I, GEORGE E. BURT- scHER, a citizen of the UnitedStates, residing at Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Hose-Clamp Tools, ofwhich the following is a specification.

My invention relates to hose clamp tools and the. object of my inventionis to provide a hoseclamp tool which shall be simpleI of construction,of low cost to manufacture and which shall be easy to operate.

The device is adapt-ed for securing a coupling member to a hose bysecurely fastening or clamping a wire loop about the same. For thispurpose a loop of wire is bent about the hose andthe free ends of thewire are passed through the loop and bent back after the wire has beendrawn tight. It is extremely diflicult to draw the loop tight enough tohold the coupling memberin the hose and thenV bend the end ,of the wiresback before they slip.

The urpose of my invention is to provide a simp e and efficient tool forthis purpose.,

My invention consists generally in a screw having a wedge shaped b ockswlveled to the end thereof, the block having a groove to receive theloop portion of the wire, a block threaded on said screw 'and having. apair of holes to receive the ends of the wire, the holes being arrangedone on each side of the screw and parallel therewith and a suitabledevice on the end of the screw for turning the same.

My invention further consists in various details of construction andarrangements of parts all as will be hereinafter fully described andparticularly pointed out in the claims.'

My invention will be more readily understood by reference to theaccompanying drawings forming apart of this specification and in which,

Figure 1 is aperspective view of a clamp ing tool embodying my inventionin its preferred form, -illustratin the device in operation, Fig. y2 isa side e evation of the wedge shaped block," and Fig. 3 is alongitudinal section of the` traveling block.

Referring to the drawings, -1 indicates a screw, threaded throughout itslength and provided with a butterfly head or handle, 2 by which it maybe turned. Swiveled tothe opposite end of the screw, 1 is a wedge shapedblock., 3 having a longitudinal groove, 4 eX- tending across its loweredge. The groove, 4 is adapted to receive the loop, A, of the wlre clampand by being wedge shaped with the narrow edge at the bottom it is freeto turn about the loop to properly bend the wire.

Threaded upon the screw, 1 is a block, 5 having a pair of holes, 6 toreceive the ends of the wire. The holes, 6 areal-ranged one on each sideof the screw and parallel therewith. The holes, 6 are of small anduniform dialneter for substantially half way through the block, afterwhich they are enlarged into the recesses, 7 which lextend through thesides of the clamp. This permits the free ends of the .wire to be morefreely drawn through the` holes andto be then bent laterally through thesides of the recesses and twisted together on the side of the block. V

In using the device a piece' of wire is looped and its free ends'bentabout the hose and passed throu h the loop. The ends, B are then passedt rough the holes, 6 in the block 5. The block, 3 is then placed on theloop, A, the loop resting in the groove, 4, and the ends of the wiresdrawn through the sides of the recesses, 7 and twisted together as at (lon the-side of the block, 5. The screwis then turned drawing ,the wiretight about the hose. When the wire approaches the breaking strain, thetool is turned back with the loop A as a pivot bending the wires iirmlyabout Ythe loop after which they may be cut oil.

Having described my inventlon what I claim as new and desire/Lto secureby Letters Patent isz' f In a device of the class described, a screwhaving a grooved wedge shaped block swiveled to one end thereof incombination witha 'block threaded on said screw said block having a pairof wire receiving holes extending therethrough parallel with the screwand one upon each side thereof, said holes terminating in enlargedrecesses extending -through the side and top of the block, said wedgeshaped block being adapted to engage the -loop of a wire clamp the freeends of which are passed through said holes and recesses and twistedupon the outside of the block, substantially as described.

In testimony whereof -I.have signed my name to this specification in thepresence of two subscribing witnesses.
